To all whom it may concern:

Be it known that I, JACOBUS J AN WILLEM Hanonm VAN DER Toonu, a subject of the Queen of the Netherlands, residing at Nas- 5 sauplein 19, The Hague, Kingdom of the Netherlands, have invented certain new and useful Improvementsin Plastic Composition, of which the following is a specification.

-The object of my invention is a method for producing a composition for the purpose of manufacturing building elements, serving for the construction or erection of walls, face-work, walls of dressed or worked stone,

5 front or retaining walls, masonry work of any kind, columns or stanchions, casings, .caissons, and buildings of any kind, the characteristic feature of which consists in the composition of cement, with granular 0 titaniferous iron (titaniferous iron oxid) and water; and the object of my invention consists further in making the said objects from the said composition.

a In the manufacture of artificial stones as coping stones, or concrete curbstones, or of artificial stones of any kind, as pavings, or artificial block pavements (cobble stones), as they are hitherto manufactured, a composition is used, which consists of cement, sand and water. Constructions made of this known material do not however answer as to the practical requirements, especially not as to the compressional strength of the composition so produced, and of the constructions made from and with the same, and also not as to the quickness required in the settinIg of the cement.

t has been found that beton blocks of very large size, such as used at harbor constructional works, as for breakwaters, or for rafting the bottoms of docks, are crushed by and removed from their seat by heavy seas for the reason, that due to their small specific gravity, they do not offer sufficient compressional strength against destructive.

powers.

It is found in ractice that articles formed of my plastic composition'are more suitable for substitution of natural stone, when the composition includes an element which lends to the increasing of the specific avity of the article, since the same will 0 er greater resistance against wear as bodies of inferior I specific strength; further that with seaand riverwork in general, and with the Specification of Letters Patent.

of fortifications, an artificial material havmg great hardness, great specific gravity and great compressional strength, and havmg further the capacity of quick setting, Wlll'be of great utility, and will offer great 5 advantages beyond the concretes (betons) used hitherto.

Now, the object of my present invention is a double one and consists: (1) in the method of providing for and in the manufacture as 5 a new industrial product of a composition, having the said properties of great specific gravity, of great compressional strength, and of quick setting capacity; and (2) to provide means for further improving of the said (plroperties of the composition, made accor 'ng to my present invention, especially for improving the setting capacity of the same.

Ad 1. In order to obtain as a new industrial article the composition suitable for making artificial stone or of constructions and builders work of the character above described, as coping stones, concrete curbstones, pavings, artificial block pavements, 30 concrete constructions, further for executin water works, fortifications and the like,-

Due to the 1 eat specific avi u I titaniferou 1r 0 u position proby mixing titaniferous iron with cement,-a reat s cific wei ht'is imparted to the constructions or builder-work, or the constructional elements made or manufactured with the said composition. The specific gravit of such manufactures is considerably higher than that of the ordina beton constructions, or of bodies of any kin made from ordinary concrete.

Due to the great adhesion of the cement and titan iferous iron with regard to each other,and due further to the fact, that the coefficient of expansion of the cement and of the titaniferous iron uniform or nearly =uniform one with respect to the other, all
